Abstract
The utility model relates to the field of online high-pressure water descaling, and discloses a descaling water purging device, which comprises a purging header pipe, a connecting hose, a prefabricated pipe and a descaling pipe; the purging manifold is connected with the prefabricated pipe through the connecting hose, and the other end of the prefabricated pipe is connected with the descaling pipe and arranged in front of the descaling backflushing manifold. The utility model provides a descaling water sweeps device, when the rolling piece passes through the roughing mill, when the secondary oxide scale is clear away with the high pressure water to the roughing mill entrance side, descaling water sweeps device and opens, sweeps the descaling water that the rolling piece surface carried to when guaranteeing next one time rolling, rolling piece surface and core temperature resume basic unanimity, avoided rolling piece surface and core material to produce the sclerosis of different degrees.
Description
Technical field
The utility model relates to online high-pressure water descaling technical field, particularly a kind of de-scaling water blow device.
Background technology
In metal rolled field, the online high pressure water descaling device that is widely used is removed the secondary oxidation iron sheet, avoids under the effect of roll-force at present, and the secondary oxidation iron sheet is pressed into the metal surface, forms to be mingled with and scar.But during de-scaling,, will cause material production sclerosis in various degree on rolled piece surface and heart portion thus because a large amount of de-scaling water of rolled piece surface coverage must cause the temperature drop on rolled piece surface.
Summary of the invention
The utility model technical problem to be solved provides a kind of a large amount of de-scaling water of removing the rolled piece surface coverage, makes rolled piece surface and heart portion temperature recover the de-scaling water blow device of basically identical.
For solving the problems of the technologies described above, the utility model provides a kind of de-scaling water blow device, comprises de-scaling pipe, scavenging header, connection flexible pipe, prefabricated pipe;
Said scavenging header is connected with said prefabricated pipe through said connection flexible pipe, and the other end of prefabricated pipe is connected with the de-scaling pipe, is arranged in before the de-scaling recoil collector.
Further, have the purge nozzle reverse on the said scavenging header with the roll line direction.
Further, said de-scaling water blow device also comprises: the collector fixture, and said scavenging header is fixed by said collector fixture, and the collector fixture is welded on the edger roll maintenance platform crossbeam.
Further, said collector fixture comprises: the first collector fixture, the second collector fixture, the 3rd collector fixture, the 4th collector fixture;
Said scavenging header is fixed together with the said first collector fixture, the second collector fixture, the 3rd collector fixture, the 4th collector fixture respectively.
Further, said prefabricated pipe is provided with Hand-operated butterfly valve.
The de-scaling water blow device that the utility model provides can purge the de-scaling water that carries on the rolled piece surface, thereby when guaranteeing that down a time is rolling, basically identical is recovered with heart portion temperature in the rolled piece surface, avoids the material production sclerosis in various degree of the surperficial and heart portion of rolled piece.
Description of drawings
The structural representation of the de-scaling water blow device that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Referring to Fig. 1, a kind of de-scaling water blow device that the utility model embodiment provides comprises de-scaling pipe 5, scavenging header 1, connects flexible pipe 4, prefabricated pipe 7, collector fixture.Scavenging header is connected with prefabricated pipe through said connection flexible pipe, and the other end of prefabricated pipe is connected with the de-scaling pipe, and is arranged in before the de-scaling recoil collector.Scavenging header 1 has several and the reverse purge nozzle 3 of roll line direction, and scavenging header 1 is fixed by the collector fixture, and the collector fixture is welded on the edger roll maintenance platform crossbeam; Prefabricated pipe 7 is provided with Hand-operated butterfly valve 6.
The collector fixture comprises: the first collector fixture 21, the second collector fixture 22, the 3rd collector fixture 23, the 4th collector fixture 24; Four different parts of scavenging header are separately fixed on the first collector fixture 21, the second collector fixture 22, the 3rd collector fixture 23, the 4th collector fixture 24.
Rolled piece passes through roughing mill; When the roughing mill entrance side is removed the secondary oxidation iron sheet with water under high pressure; Open de-scaling water blow device through the Hand-operated butterfly valve on the prefabricated pipe 7, purge water from de-scaling pipe 5 through prefabricated pipe 7 be connected flexible pipe 4 and flow to scavenging header 1, from the purge nozzle 3 of scavenging header 1, spray; Thereby purge the de-scaling water that carries on the rolled piece surface; Thereby when guaranteeing that a time is rolling down, rolled piece surface and heart portion temperature are recovered basically identical, avoid rolled piece surface and heart portion will cause material production sclerosis in various degree.
The de-scaling water blow device that the utility model provides has following beneficial effect:
1. a large amount of de-scaling water that can remove the rolled piece surface coverage make rolled piece surface and heart portion temperature recover basically identical, avoid the material production sclerosis in various degree of rolled piece surface and heart portion.
2. simple in structure, control is convenient, is convenient on engineering, realize.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
